Background technology
Early, development is fast, and technical merit is high in external potato harvester development starting.The big-and-middle-sized combined harvester of main production, it is bulky, complicated structure, and price comparison is expensive, and China's potato harvester development is started late.China is one of potato country with fastest developing speed, and national potato planting area reaches 1,350 ten thousand hm 2, great majority are planted in mountain region or hilly and gully area, and results are main, and by manpower animal power, production efficiency is low, and labour intensity is large, governs further developing of Potato Industry.The extensive film-covering planting potato in northwest arid area, realizing potato harvest machineization has become vast plantation family strong desire and the market demand.The separator that current existing potato harvester adopts is generally chain-type, connect the chain of bar strip in both sides, because the width of chain is larger, cause potato when gathering in the crops the potato of full film double-furrow plantation like this, there is soil block and be separated the problems such as clean, exposed potato rate is lower, existing the clearner chain of chain in both sides cannot realize thoroughly being separated.
Summary of the invention
The purpose of this utility model is avoid the defect of prior art and provide a kind of chain guide formula potato harvester, efficiently solves prior art Problems existing.
For achieving the above object, the technical scheme that the utility model is taked is: described chain guide formula potato harvester, comprise frame, the frame front end being characterized in described is provided with the draw-gear and the transmission device that is connected with tractor motive power output shaft that mount with rear tractor three-point hitch, the power take-off of transmission device is connected with separator, frame forward lower part is provided with excavating gear, and in separator, correspondence is provided with vibrating wheels, and frame rear end bottom is also provided with running gear; Described excavating gear comprises left shovel, middle shovel, right shovel and weld holder; Described separator comprises bar strip, chain and guide rail mechanism.
Described weld holder is arranged in frame, and described left shovel and right shovel are monolithic, and middle shovel is four pieces, and left shovel, middle shovel and right shovel are welded on weld holder equably, and the longitudinal profile of excavating gear, in " ~ " shape, improves the ability of burying with hack.
The mid point of described bar strip is fixed on chain, drives bar strip to move in guide rail mechanism during chain rotation, and native potato is through shaking, loosening on chain, and vibration, fragmentation, play the effect of thoroughly separation soil block.
Described guide rail mechanism comprises fixed head, guide rail and set bolt, and fixed head is by set bolt fixed frame; Drive bar strip to move in guide rail when chain rotates, guide supporting bar strip also prevents bar strip from swinging up and down.
The beneficial effects of the utility model are: described chain guide formula potato harvester, this machine disposablely can complete the operations such as the excavation of two row potatos, native potato separation, the chain of separator is in the middle of bar strip, move in bar strip both sides in guide rail, separator serves conveying and is thoroughly separated native potato, decrease the situation that potato is covered by soil, and novel structure, exposed potato rate are high.

Fig. 4 is guide rail mechanism structural representation of the present utility model.
Shown in figure: 1. transmission device; 2. draw-gear; 3. excavating gear; Shovel, the right shovel of 3-3. in the left shovel of 3-1., 3-2.; 3-4. weld holder; 4. separator; 4-1. bar strip, 4-2. chain, 4-3. guide rail mechanism; 4-3-1. fixed head, 4-3-2. guide rail, 4-3-3. set bolt; 5. running gear; 6. vibrating wheels; 7. frame.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figures 1 to 4, described chain guide formula potato harvester, comprise frame 7, frame 7 front end being characterized in described is provided with the draw-gear 2 and the transmission device 1 that is connected with tractor motive power output shaft that mount with rear tractor three-point hitch, the power take-off of transmission device 1 is connected with separator 4, frame 7 forward lower part is provided with excavating gear 3, and in separator 4, correspondence is provided with vibrating wheels 6, and frame 7 rear end lower is also provided with running gear 5; Described excavating gear 3 comprises left shovel 3-1, middle shovel 3-2, right shovel 3-3 and weld holder 3-4; Described separator 4 comprises bar strip 4-1, chain 4-2 and guide rail mechanism 4-3.
Further, described weld holder 3-4 is arranged in frame 7, described left shovel 3-1 and right shovel 3-3 is monolithic, middle shovel 3-2 is four pieces, left shovel 3-1, middle shovel 3-2 and right shovel 3-3 are welded on weld holder 3-4 equably, the longitudinal profile of excavating gear 3, in " ~ " shape, improves the ability of burying with hack.
Further, the mid point of described bar strip 4-1 is fixed on chain 4-2, drives bar strip 4-1 to move in guide rail mechanism 4-3 during chain 4-2 rotation, and native potato is through shaking, loosening on chain, and vibration, fragmentation, play the effect of thoroughly separation soil block.
Further, described guide rail mechanism 4-3 comprises fixed head 4-3-1, guide rail 4-3-2 and set bolt 4-3-3, and fixed head 4-3-1 is by set bolt 4-3-3 fixed frame 7; Drive bar strip 4-1 to move in guide rail 4-3-2 when chain 4-2 rotates, guide rail 4-3-2 supports bar strip 4-1 and prevents bar strip 4-1 from swinging up and down.Native potato is transported on separator, and the Area comparison that native potato accounts on the both sides of chain is large, and native potato is through shaking, loosening on chain, and vibration, fragmentation, play the effect of thoroughly separation soil block.
Described chain guide formula potato harvester, when farm work, its draw-gear 2 and rear tractor three-point hitch mounts, the advance of tractor-drawn chain guide formula potato harvester, and digger blade 3 carries out excavation of burying under the effect of transmission device 1 and running gear 5; The native potato excavated and stem stalk are transported to separator 4, separator 4 is carried it and is thoroughly separated under the effect of transmission device 1 with vibrating wheels 6, the separator of this machine can improve native potato separative efficiency, decrease the situation that potato is covered by soil, and novel structure, exposed potato rate is high.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
